European regional assessment: Least Concern (LC)
EU 27 regional assessment: Least Concern (LC)

secalinum is regionally assessed as Least Concern as it is widely distributed in northern, middle, east, southeastern and southwestern Europe. However, although  it is widely distributed in many parts of its range, there are reported population declines in some countries and it is considered to be threatened in Germany. There is currently no knowledge available about the threats to this species; therefore, research is needed to identify the cause of these population declines. Population and habitat monitoring is also recommended at national level.

Geographic Range [top]

Range Description:H. secalinum is native to northern, middle, east, southeastern and southwestern Europe, as well as to Macaronesia and northern Africa (Valdés and Scholz; with contributions from Raab-Straube and Parolly 2009, USDA, ARS, National Genetic Resources Progam 2010).

Knowledge of its national distribution in Europe is as follows:

  • Greece: in the north and on Corfu island (Damanakis and Economou 1986).
  • France: widespread; occurs in the majority of departments excluding Nord, Paris, Hauts-de-Seine and Val-de-Marne to the north, Territoire de Belfort, Doubs, Rhône, Isère and Savoie to the east, Alpes-de-Haute-Provence to the southeast, Creuse in the centre and five departments to the southwest (Association Tela Botanica 2000–2010).
  • Germany: occurs mainly in the north on the coasts of the Baltic and Northern Seas, as well as in plains and lowlands in the central area of the country (Bundesamt für Naturschutz 2010).
  • UK: widespread throughout the southern half of England, with a patchy distribution in Wales (Preston et al. 2002). All occurrences in Scotland and Northern Ireland are recorded by Preston et al. (2002) as being alien.
  • Ireland: has a patchy distribution throughout the country (Preston et al. 2002).
  • Netherlands: occurs along the large rivers and in coastal areas throughout the country (Mennema et al. 1985).
Countries occurrence:
Belgium; Bulgaria; Denmark; France (France (mainland)); Germany; Greece (Greece (mainland)); Ireland; Italy (Italy (mainland), Sicilia); Luxembourg; Macedonia, the former Yugoslav Republic of; Malta; Netherlands; Poland; Portugal (Madeira, Portugal (mainland)); Slovenia; Spain (Spain (mainland)); Sweden; Switzerland; Ukraine (Krym); United Kingdom (Great Britain)

Population [top]

Population:Knowledge of the European population at national level is as follows:

  • Greece: not frequent.
  • Germany: the population is decreasing, mainly in southern parts of its range.
  • UK: according to Preston et al. (2002), this species’ distribution has declined very slightly in the north and west of Britain.
  • Ireland: according to Preston et al. (2002), this species’overall distribution is stable.
  • Netherlands: before 1950 the species occurred in 479 hour-squares and after 1950 in 531 (Mennema et al. 1985). Tamis et al. (2003) report that the species occurs in 1,001–3,000 km grid squares.
Current Population Trend:Unknown
Additional data:
Population severely fragmented:No

Habitat and Ecology [top]

Habitat and Ecology:In Germany, this species grows in coastal salt meadows, pastures and grasslands (Bundesamt für Naturschutz 2010). In the UK, this lowland species grows in meadows and pastures, along roadsides and in river valley floodplains—it prefers sticky, clay soils (Preston et al. 2002). At the coast it is often found in grazing marsh grasslands and on earthen sea walls (Preston et al. 2002). In the Netherlands, it grows in brackish wet soils and in humid and very fertile soils (Tamis et al. 2003).

Use and Trade [top]

Use and Trade: H. secalinum is a tertiary wild relative of and potential gene donor to barley, H. vulgare.

Threats [top]

Major Threat(s):

Further research is needed to gather information about the potential threats to this species.

Conservation Actions [top]

Conservation Actions: The genus Hordeum is listed in Annex I of the International Treaty on Plant Genetic Resources for Food and Agriculture.

H. secalinum is listed as Least Concern in Denmark (Den Danske Rødliste 2010). It is not threatened in the Netherlands.

In Germany, it is evaluated as endangered (Red List category 3) but it is not protected (Bundesamt für Naturschutz 2010). In France, it is protected in the region of Alsace (Association Tela Botanica 2000–2010).

EURISCO reports 23 germplasm accessions of H. secalinum held in European genebanks, 20 of which are reported to be of wild or weedy origin. Of the wild accessions, 18 originate from within Europe (EURISCO Catalogue 2010).
